Abstract

PURPOSE:To improve the exhausting performance of a ventilator and to enable to install a ventilating fan in an invisible position, by providing a ventilating duct which is faced to the mounting table of a gas range, and by interconnecting the ventilating port in the upper position, facing to the range, to the ventilating fan which is installed in the lower position. CONSTITUTION:A ventilating duct 7 of which section is rectangular is monolithically provided to the rear part of a kitchen unit 3, consisting of a range mounting table 1 with a range 2 fixedly put on the table. A ventilating port 4 opened to the range 2 is provided to the upper end of the ventilating duct 7, which is interconnected to a ventilating fan 6, being provided to the surface of an external wall 9 contacting to a ventilating duct 7. A hood 10 to prevent heated gas from rising, consisting of a rising piece 11 and a hood body 12, is provided to the upper position of said range 2.

Description

[Detailed Description of the Invention] The present invention relates to a combustion gas exhaust device that exhausts gas emitted from a microwave oven to the outdoors.The microwave oven can be installed anywhere, and the exhaust performance is good (and the ventilation fan can be used indoors). This provides an invisible combustion gas exhaust system.

Conventionally, the ventilation fan that exhausts the gas emitted from the range to the outdoors is installed on the outside wall above the range, so the range can only be installed in a position facing the outside wall, and it cannot be installed in a location away from the outside wall. In addition, carbon dioxide, which is heavier than air, fills the space below and does not rise to the level of the ventilation fan, making it impossible to ventilate the room.Furthermore, the ventilation fan is visible from inside the room, making the wall look unsightly.

The present invention was made in order to solve the above-mentioned conventional problems.The microwave oven is placed on the microwave support stand, and a ventilation opening is provided facing the microwave oven of the microwave oven. The present invention provides a combustion gas exhaust device characterized in that a ventilation duct is provided that communicates from the opening to a ventilation fan provided below the ventilation opening.

Hereinafter, the present invention will be explained in detail based on the drawings.

For example, as shown in FIGS. 1 and 2, the combustion gas exhaust system of the present invention is constructed by placing a range 2, such as a gas range or an electric range, on a range support stand 1 on a floor surface 8. A kitchen appliance 3 is placed therein, and a ventilation duct 7 having a rectangular cross section is provided integrally at the rear of the kitchen appliance 3. A ventilation port 4 that opens toward the range 2 is provided on the top surface of the ventilation duct 7, and the ventilation port 4 has a mesh shape to prevent dust and the like from entering the ventilation duct 7. The microwave oven 1 shown in FIG. 2 is placed facing an outer wall surface 9, and the ventilation duct 7 is in contact with the outer wall surface 9. A ventilation fan 6 is provided on an outer wall surface 9 in contact with the ventilation duct 7 and communicates with the ventilation duct 7.

In this operating state, as shown in FIG. 2, when the ventilation fan 8 is turned on, combustion gas such as smoke discharged from the range 1 during cooking is sucked into the ventilation opening 4 and passes through the ventilation duct 7 to the ventilation fan 8. is discharged outdoors.

Reference numeral 5 designates an outdoor hood that prevents rainwater, dirt, etc. from entering the room from the ventilation fan 8.

As shown in FIG. 2, if a heat rise prevention hood 10 is provided above the range 1, combustion gas such as smoke discharged from the range 1 will not rise above the heat rise prevention hood 10. First, the combustion gas accumulates under the rise prevention hood 10, and the combustion gas is reliably discharged to the outside from the ventilation port 4, which is good.

To explain the details of the rise prevention hood 10, the rise prevention hood 10 includes a rising piece 11 connected to the lower upper end of the ventilation duct 4, and a generally groove-shaped cross section connected to the rising piece 11 and opening at the bottom. It consists of a hood body 12. This hood body 12 is located above the range 1.

Fig. 3 shows the microwave oven 1 installed at a position away from the outer wall surface 9, and the ventilation duct 7 running along the rear surface of the kitchen appliance 3 and reaching the bottom surface of the kitchen appliance 3, with a cross-sectional shape. . The ventilation duct 7 is in contact with a floor surface 8, and the floor surface 8 is provided with a ventilation fan 6 that communicates with the underfloor. In this embodiment, the gas discharged from the range 1 is sucked into the ventilation port, passes through the L-shaped ventilation duct 7, and is discharged from the ventilation fan 6 on the floor surface 8 to below the floor.

Note 11 is the foundation of the building.

As mentioned above, according to the ventilation system of the present invention, since the ventilation fan is installed below the ventilation duct that is installed facing the kitchen appliance, the ventilation fan can be installed not only on the outer wall surface but also on the floor surface. The installation location of the range is not limited to a position facing the outside wall, so it can be installed anywhere, and heavy gases such as carbon dioxide, which are heavier than air, can also be exhausted because the ventilation port is located next to the range. Furthermore, since the ventilation fan is installed behind the kitchen appliances, it is not visible from inside the room and looks good.
